Answer 1

Calculation of Hay Consumption in January and February

To calculate the total amount of hay consumed in January and February, we need to consider the increase in hay consumption from January to February.

According to the information provided, in January, 14% of the total hay was consumed, while in February, 20% of the total hay was consumed. Additionally, it is mentioned that in February, 36 tons more hay was consumed compared to January.

Let's assume the total amount of hay consumed in January is x tons. Based on this assumption, we can calculate the total amount of hay consumed in February.

In January, 14% of the total hay was consumed, which can be expressed as 0.14x tons.

In February, 20% of the total hay was consumed, which can be expressed as 0.20(x + 36) tons. (Adding 36 tons to account for the increase in hay consumption)

To find the total amount of hay consumed in January and February together, we can add the hay consumption in January and February:

0.14x + 0.20(x + 36) = Total hay consumption in January and February

Now, let's solve this equation to find the total amount of hay consumed in January and February.

0.14x + 0.20(x + 36) = Total hay consumption in January and February

0.14x + 0.20x + 7.2 = Total hay consumption in January and February

0.34x + 7.2 = Total hay consumption in January and February

0.34x = Total hay consumption in January and February - 7.2

0.34x = Total hay consumption in January and February - 7.2

x = (Total hay consumption in January and February - 7.2) / 0.34

Now, we can substitute the given values to find the total amount of hay consumed in January and February.

x = (Total hay consumption in January and February - 7.2) / 0.34

Please note that the exact values for the total hay consumption in January and February are not provided in the question. Therefore, we cannot calculate the exact answer without this information.
